Abstract

MÉTODO, DISPOSITIVO E SISTEMA DE DETECÇÃO DE CONECTIVIDADE DE ÁRVORE P2MP. Este pedido fornece um método, um dispositivo e um sistema de detecção de conectividade de árvore P2MP. O método é aplicado ao domínio de SR. O domínio de SR inclui uma árvore P2MP. A árvore P2MP inclui um primeiro nó. O primeiro nó é um nó raiz ou um nó de replicação intermediário da árvore P2MP. O método inclui: o primeiro nó determina um primeiro nó de próximo salto do primeiro nó com base em informação de ramo de replicação; e o primeiro nó envia uma primeira mensagem de solicitação para o primeiro nó de próximo salto. A primeira mensagem de solicitação inclui um identificador de segmento SID do primeiro nó de próximo salto. A primeira mensagem de solicitação inclui um primeiro identificador. O primeiro identificador indica que a primeira mensagem de solicitação é para detecção de conectividade.P2MP TREE CONNECTIVITY DETECTION METHOD, DEVICE AND SYSTEM. This application provides a method, device, and system for detecting P2MP tree connectivity. The method is applied to the SR domain. The SR domain includes a P2MP tree. The P2MP tree includes a first node. The first node is a root node or an intermediate replication node of the P2MP tree. The method includes: the first node determines a first node's next hop first node based on replication branch information; and the first node sends a first request message to the first next hop node. The first request message includes a segment identifier SID of the first next-hop node. The first request message includes a first identifier. The first identifier indicates that the first request message is for connectivity detection.
